Intersections are necessary in today’s society but can pose risks to safety due to the high speeds and dangerous angles of conflict that are often involved with them. There are a number of methods that can be employed to improve safety; this report discusses such methods and their practicality.

The initial research of the thesis identified an intersection in Coolalinga, Northern Territory to be unsafe to road users and therefore became the subject of the thesis. The Coolalinga area is rapidly developing and a local intersection that feeds two service roads onto the Stuart Highway is believed to be inadequate to service the growing population effectively and is threatening road user safety. This threat will continue to grow as the area expands. Research, crash data analysis of Darwin intersections and site investigations were used to determine a number of solutions and compare them in terms of cost effectiveness, efficiency, practicality and safety.
